CURPORATION OF NEW YORK GAS MANUFACTUIELE Application filed September 23, 1924. Serial No. 739,289.

This invention relates to water gas manuy sets adapted to practice the back-run process such on the lining takes place.

and in which the steam required for the backrun is produced by introducing water at a suitable point in the plant and utilizing the heat content of the plant to convert it into steam. n l

According to thepresent invention the water is introduced into the. apparatus in such a Way that contact thereof with the walls or lining of the apparatus is prevented, 1. e., substantially all of the water is converted into steam before it can come in contact with the apparatus of the plant. For this purpose a device is used for introducing the water into the plant, preferably the superheater, which is so constructed and positioned that the water is introduced at the top of the superheater relatively distant from the lining thereof and in a finely divided condition preferably as a mist or fogythe net result being` that substan tially no deposition or contact of water as In this way the' disintegration and pulverization which tends to result from contact ofwater with the highly heated lining is avoided, at the Sametime the heat content ot the apparatus is etliciently utilized for theproduction ot the desired high temperature steam, and only the top of the superheater is subjected to any appreciable cooling effects.

One object ot my invention is to cheapen the production of water gas manufacture by providing a water spray properly constructed and positioned within the superheater of the gas plant so as to do away with the necessity for the introduction of steam into the superheater. Another object is to provide means orpermitting the quick and simple removal ot the water spray from the superheater when it is desired to close the plant.

W'ith the above, and other objects, in View,`

my invention consists in the arrangement, combination and construction of the various parts of my improved device as described in the specification, claimedin my claims and shown in the accompanying drawings, in which:

Fig. 1 is a side elevation of a gas plant in which my invention is employed. n

Fig. 2 is a sectional view partly in elevation taken on line .2-2 of Fig. 1.

F ig. 3 is a detail view in vertical section of the spray utilized in my invention.

'l have shown the conventional carburetted watergas plant, consisting et a generator 5, a carburetor 6, a superheater T and a wash box 8. An air blast pipe 9 is connected through the pipe 10 with the bottom of the generator and a quick shut-oil valve 1l is utilized *for closing the blasting line when the blasting operation is completed. Steam may then be furnished from a suitable source of supply through the passages 1:2, 13 and 10 into the bottom ot' the generator for making the customary up run of gas.

The customary connections such as the passage 14 from the generator to the carburetor, r

the passage 15 from the carburetor to the superheater and the passage 16 Jfrom the superheater to the wash box aroused. Likewise heater, utilize a housing` or nozzle 19 which may be welded to the metal casing of the superhoater as at Q0. The water connection 21 leading to the spray 1S passes through this housing 19 and the stuffing box 40, and is connected at its outer end to a hose, or other iexible connection, not shown, so that the spray 18 may be withdrawn from the superheater.

The stuiiing box 40 is provided with a 'flange 41 which is bolted by bolts 42 to the movable iange 43 on the housing 1S), the fiange 44 on the end ot the housing being positioned between the flanges 41 and 43.

Water is drawn by means of a pump 23 from any suitable source ot supply, is passed into a pressuretank 24 and thence through the pipe 25, a strainer 26, suitable piping 27, and either through the piping 45 or the pip ing 22, into the spray. Along the piping Q7 are provided a pressure gauge 28, a Water meter 29 and a quick-shut-ot valve 30. 'I'he passage of the water through the piping 45, carries it through coils 46 disposed around the superheater oiftake 16, with the result that the Water is" preheated during the 11p-run operation, so that less heat and time are .required to convert it into steam for use during the back-run operation. The coils 46 should be of suiiicent capacity to hold an ample i Water supply for the back-run cycle inasmuch as no appreciable heat is passed into the ofitake 16 during the back-run. t

I have provided valves 47, 48 and 49, so'that when water is passed4 through the coils 46, the valve 49 may be closed and the other tw o opened, While when the Water 1s passed d1- rectly into'the spray, Without preheating, the valves 47 and 48 may be closed and the'valve y 49 opened. l

When it is desired to close the plant so that no more water is supplied in the top of the superheatenthe spray 18 is drawn out into the housing or nozzle 19 so as to be completely removed from the superheater.

It will be noted that the face of the spray 18 is in'effect corrugated, as shown in Fig. 3, and the spray openings 31 are positioned in the angled sides of the corrugations so as to cause the fine streams of water to cross each other and tend to' break into a line'spray or fog. The very small openings in the spray itself will also assist in bringing about this result.

With an arrangement such as above described, the fine spray of water will be imheater for-use during the Vback-run combustible gas-making cycle.

2. A Water gas plant comprising a gener-v supplying water to said nozzle, saidnozzle.

being positioned away from the superheater -walls and directed to feed said water upwards, whereby contact of said water with the superheater walls. is substantially preventediand the water is generated into steam for use during the back-run combustible gasmaking cycle.

-mediately vaporiz'ed by the intense heat present in the superheater so that the steam will have been generated before the Water can strike the sides or Walls of the superheater, thus preventing disintegration of the superheater walls.

It is obvious that various changes may be v made in the arrangement, combination and construction of the various parts of my improved device without departing from the spirit of my invention, and it is my intention to cover by my claims such changes as may be reasonably included within the scope thereof. y y

- What I claim is:

1. A' Water gas plant comprising a single generator, a single carburetor, a single superheater and wash box connected in series, a passage leading from the base of the generator to the wash boX, spray nozzle positioned Within the superheater at substantially the top thereof, said nozzle having a pipe connection extending through the superheater wall', whereby said nozzleis positioned away from said superan upwardly directed heated Wall, and means for supplying water lOLl
